How does an X-ray work?
X-rays are electromagnetic waves that are like light. They can penetrate materials with masses to different levels. When the x-rays hit the film, it creates an image which shows it like a light would. Since bone, fat, muscle, tumors and other structures all absorb x-rays at different levels, the image on the film lets you see different distinct structures inside the body. This is because of the various levels of exposure on the film.
What is radioactivity? What is radiation?
Unstable atomic nuclei will suddening begin to decompose to form a nuclei with a higher stability. This decomposition process is called radioactivity. The energy and particles which are released durig the decomposition process are called radiation. When an unstable nuclei decomposes in nature, the process is referred to as natural radioactivity. When an unstable nuclei is prepared in the laboratory the decomposition is called induced radioactivity.
How the film captures the picture?
The x-ray machine has 3 main components to it. The componets are a vaccum tube which has a cathode and an anode which are most often made of the element tungsten. The cathode is a heated filament. When the electric current passes through the filament the temperture goes up extremely. When it reaches a very high temperture the filament begins releasing negatively charged electrons from the surface. Then the positively charged tungsten anode component of the x-ray attracts these electrons with a large force, pulling them through the vacuum tube at a high speed. When an electron collides with a tungsten atom, an electron in one of the atom’s lower orbitals gets knocked away. Then after an electron from a higher orbital takes the place of the removed elect...

The third type of radiation is gamma radiation. Gamma radiation and X-rays are part of the electromagnetic radiation like visible light, radio waves, and ultraviolet light. These electromagnetic radiations differ by the amount of energy's they have. Gamma radiation can penerate through most materials including skin, it can travel very deep in human tissues as well. Gamma radiation has abosolutly no mass and is able to travle in the speed of light. It is very fast and very strong. When radioactive materials release gamma radiation it can be both externally and internally hazards for humans.
That is why many preganant women do not take a lot of X-rays. It can be harmful for the fetus inside. The radiation that comes from these rays can cause abnormalities and other defects later in life.
Physicists started to realize that stable nuclei can be converted to unstable nuclei. Through such process, they discovered that heavy nuclei can undergo nuclear fission. While testing, they added a neutron to an isotope of Uranium 235. This resulted Uranium 235 to become unstable and break down into Barium and Krypton, releasing two to three more neutrons. The breakdown of Uranium 235 is called “fission”.

of the usage of radiation and effects it can cause an unborn foetus. A standard pregnancy check, if not worked right and asked correctly could imply stereotyping and thus cause great offence to the patient and/ or their family. Radiographers need to ensure that they justify to the patient (and in some cases family) why they are asking for the pregnancy check. For example instead of asking ‘are you pregnant?’ or ‘could you be pregnant?’ radiographers should instead ask ‘because this examination involves the usage of radiation, is there any chance that you could be pregnant?’
In short, this manual provides an overview of radiography, x-ray equipment, the ALARA principle, infection control, film and film processing. The purpose is to further the understanding of these concepts and aid in office implementation and improve patient and operator safety.
“Alpha decay (4x2) is a radioactive process in which a particle with two neutrons and two protons is ejected from the nucleus of a radioactive atom.” The mass number is decreased by four and the atomic number is decreased by two. “Beta decay (e-) occurs when, in a nucleus with too many protons or too many
How does the X-ray work? Well first off let me tell you the difference of light rays and X-rays. The light rays are visible light waves and x-rays is a light that is smaller than atoms in your body. You can’t see them with the naked eye like sun rays. X-rays will only pick up items and body parts that are hard and also made of calcium. That light will then project your muscle that would look like a light gray and your bone structure that will be white onto a black piece of radio graphic film.
Each ray in the spectrum have different characteristics and features. Gamma rays, along with 2 others are "ionizing," meaning these waves have such a high level of energy that they can knock electrons out of atoms. Exposure to these highly energized waves can reshape atoms and molecules and cause damage to cells in natural, untouched forms and matter. This is where the separation of the advantages and dis advantages of ionizing waves occur. These changes to cells can be helpful, as when radiation is used to kill cancer cells, yet if not taken care of seriously it can be highly dangerous to the lives of us humans. Out of the electromagnetic spectrum Gamma rays hold the smallest wave length of 10 to the power of 10-10 to the power of 12. In electromagnetic radiation the wave’s frequency is ...
Radiation occurs when radioactive elements break apart. Radiation is very dangerous because it damages living things. There are three types of radiation, these are alpha particles, beta particles, and gamma rays. They are the first three letters of the Greek alphabet: alpha (a), beta (β), and gamma (ϒ). These particles and rays are produced by radioactive elements. Alpha particles are made of 2 protons and two neutrons that have separated from the nucleus, they are positively charged. Beta particles are usually made of one electron and a neutron, and have a negative charge. Gamma rays are a different sort of radiation. They are made of a stream of tiny particles called photons. Photons include the same particles that make up rays of light and are packets of energy. Gamma rays are very dangerous because they carry a lot more energy than the light people can see but are still invisible. Also released by radioactive elements are X-rays, they are similar to gamma rays but contain less energy.
I must use the same amount of enzyme each time I do an experiment so I
Gamma radiation/emission – Gamma ray emission can be found when either alpha or beta decay occurs. Gamma rays are high energy electromagnetic rays. Gamma radiation is just the excess energy of the reaction being shed off, gamma rays do not effect mass numbers or atomic numbers. 6027Co 6028Ni + 0-1e + y
To begin with. the x-ray has a long history, it is 121 years old! Back then when something was wrong they would try to “bleed” it out of you. Or use some bazar way to get rid of it. Which is not good and can cause more or worse pain to not even truly even help you in the long run. But now we have different kinds
From the unit of chemistry in grade ten science, the students have learned many things from different types of elements in the chart all the way to how each element impacts the daily life each student or even adult lives in. Some of the things I as a student have learned include how to draw the different elements in a bohr rutherford diagram, balancing chemical equations, types of chemical reactions, and even information about the different types of acids and bases. Although there were many other things in the unit, these four definately helped me learn about chemistry in a more in-depth way, as well as teaching me something very new since these were some things a few of the students had never done in the previous years. Learning this in the classroom has really opened my eyes to the world in which we live in today, many times I leave the house on a cold day and as I look upon the cold water becoming ice or even the snow falling down, I know how it is happening, why it is happening, and I can even picture the molecules solidifying as we had seen in class with many different diagrams.
...ain circuit the electrons will reach the x-ray tube where they change from electrons to photons, moving from cathode to anode. After photons have been created the x-ray beam is emitted. The e-xray beam passes through matter causing attenuation. From x-ray beam through the human body or matter photons are absorbed, passed through unaffected, and changing direction creating scattered electrons. Passing through photons are responsible for creating the image contrast and scattered photons are undesirable, lowering visible contrast. Scatter is controlled through the use of a grid. Once photons and electrons penetrate the grid they reach the PSP in a CR system. A latent image is formed in the phosphor layer of the PSP and then read by a specialized CR processor, allowing the x-ray to be viewed on a monitor. This completes the path of electrons from AC to image formation.
